Redirect Site Map To Fix The Crawl Errors

I recently opened a google.com/webmasters account to better manage my website. Over the years I have accumulated about 50 crawl errors that are reported in my account. Most of these are the result of URL changes I have made.

I wish to "redirect" these old URLs to the current URLs. My guess is that I need to provide Google with a redirect site map to fix the crawl errors. I was able to download the errors which opened on my system as an Excel file. Is there some format I need to follow, perhaps inserting the current URLs in the Excel file and sending it back.

If you want to redirect the old URLs to current ones, that's really all you need to do. You don't need to provide Google with a "redirect site map," but if any of the bad URLs are listed in your current site map they should certainly be removed, whether they're to be redirected or not -- if they don't resolve properly,. they shouldn't be listed in the sitemap.
